Database Specific Aspects of 64-bit Development

SQL Server Connectivity Aspects

If you are working in the Direct mode or developing a 32-bit application only, then the development process will not be different for you, except some peculiarities of each particular platform. But if you are developing a 64-bit application, you have to be aware of specifics of working with client libraries at design-time and run-time. To connect to a SQL Server database at design-time, you must have its 32-bit client library. You have to place it to the C:\Windows\SysWOW64 directory. This requirement flows out from the fact that RAD Studio XE2 is a 32-bit application and it cannot load 64-bit libraries at design-time. To work with a SQL Server database at run-time (64-bit application), you must have the 64-bit client library placed to the C:\Windows\System32 directory.
